<div class="textblock"><p>Fast dense optical flow computation based on robust local optical flow (RLOF) algorithms and sparse-to-dense interpolation scheme. </p>
<p>The RLOF is a fast local optical flow approach described in <a class="el" href="../../d0/de3/citelist.html#CITEREF_Senst2012">[216]</a> <a class="el" href="../../d0/de3/citelist.html#CITEREF_Senst2013">[217]</a> <a class="el" href="../../d0/de3/citelist.html#CITEREF_Senst2014">[218]</a> and <a class="el" href="../../d0/de3/citelist.html#CITEREF_Senst2016">[219]</a> similar to the pyramidal iterative Lucas-Kanade method as proposed by <a class="el" href="../../d0/de3/citelist.html#CITEREF_Bouguet00">[30]</a>. More details and experiments can be found in the following thesis <a class="el" href="../../d0/de3/citelist.html#CITEREF_Senst2019">[220]</a>. The implementation is derived from <a class="el" href="../../dc/d6b/group__video__track.html#ga473e4b886d0bcc6b65831eb88ed93323" title="Calculates an optical flow for a sparse feature set using the iterative Lucas-Kanade method with pyra...">optflow::calcOpticalFlowPyrLK()</a>.</p>
<p>The sparse-to-dense interpolation scheme allows for fast computation of dense optical flow using RLOF (see <a class="el" href="../../d0/de3/citelist.html#CITEREF_Geistert2016">[89]</a>). For this scheme the following steps are applied:</p><ol type="1">
<li>motion vector seeded at a regular sampled grid are computed. The sparsity of this grid can be configured with setGridStep</li>
<li>(optinally) errornous motion vectors are filter based on the forward backward confidence. The threshold can be configured with setForwardBackward. The filter is only applied if the threshold &gt;0 but than the runtime is doubled due to the estimation of the backward flow.</li>
<li>Vector field interpolation is applied to the motion vector set to obtain a dense vector field.</li>
</ol>
<p>For the RLOF configuration see <a class="el" href="../../d4/d91/classcv_1_1optflow_1_1RLOFOpticalFlowParameter.html" title="This is used store and set up the parameters of the robust local optical flow (RLOF) algoritm...">optflow::RLOFOpticalFlowParameter</a> for further details. Parameters have been described in <a class="el" href="../../d0/de3/citelist.html#CITEREF_Senst2012">[216]</a> <a class="el" href="../../d0/de3/citelist.html#CITEREF_Senst2013">[217]</a> <a class="el" href="../../d0/de3/citelist.html#CITEREF_Senst2014">[218]</a> and <a class="el" href="../../d0/de3/citelist.html#CITEREF_Senst2016">[219]</a>.</p>
<dl class="section note"><dt>Note</dt><dd>If the grid size is set to (1,1) and the forward backward threshold &lt;= 0 than pixelwise dense optical flow field is computed by RLOF without using interpolation.</dd>
<dd>
Note that in output, if no correspondences are found between <em>I0</em> and <em>I1</em>, the <em>flow</em> is set to 0. </dd></dl>
